SYLVESTER w. eIBBs'oF CANTON, onio- EMBROIDE RSI-FRAME Specification of Letters Patent.

Patented July 27, 1909.

Application fiIed March 16, 1909. Serial No. 483,716.

To all whom it may concern:

Be it known that I, SYLvEs'r'En WLGIBBS, a citizen of the United States,residing at Canton, in the county of Stark andStateof 5 Ohio, have invented a new and useful Improvement in Embroidery-Frames, of which the following is a specification.

The inven ion relates to a frame composed of an inner 00p and an outer ring-{collecas an embroidery. hoop, ar-

ranged to stretch and hold a fabric over the inner hoop for the purpose of embroidering the fabric. In frames of this character, difficulty has becn experienced in constructing and arranging the parts so that the fabric can first be properly adjusted and stretched to an even and uniform tension over. the inner hoop, and then tautly clamped and positively held in this relation. Further difiio culty has been found in providing a frame adapted to accomplish these results with respect to fabrics of different thickness, and

especially with respect to the thinner and more delicate fabrics which are likely to have t-heirthreads pulled or torn by the clamping action which is usually required for the thicker and coarser fabrics.

The invention relates to the use of a curved elastic wire for the clamping ring, hereinafter referred to as the ring, and of thin metal for the inner hoop, hereinafter referred to as the" hoop; and the objects of these features of the improvement are to provide a clamping ring which can be readily adjusted to meet all the varying requirements of use, and will at the same time permit fabrics of different thickness to be readily stretched and adjusted-and then positively clamped without injury thereto, and furthermore to provide a thin metal hoop shaped to furnish sufficient strength Without any exposed edges to cut the fabric, and also to make an improved joint for the hoop without overlapping ends and without the use of solder.

Further purposes of the invention pertainto the shape 0 the hoop, which is provided with a V-shapc. groove in its outer face,

against the sides of which the ring readily finds two separate and distinct zones of contact for clamping the intervening fabric; and

, also to the use of a resilient frictional material in' the bottom of the groove, against which the fabric is compressed by the ring before the same is clamped against the sides of the groove. r I

The purposes of, the invention, thus set forth in general terms, and other ancillary with anintervening fabric, andthe details of the clamping lever; Fig. 4, an enlargedfrage mcntary section of thehoop and the ring,

joint and showing the ring J clamped; Fig. 6, a view like Fig. 4, with a Similar numerals refer to similar parts The hoopl is preferably made of sheet metal or other suitable thin material and is formed with the head 2 on each edge thereof. In the simpler form of the hoop illustrated in Figs. 1,. 2 and 4, the body or web 8 of the hoop is formed with a V-shapcd groove in its outer face. convergingly inclined to the plane of the hoop and the walls thereof may be of single thickness as shown in Fig. f1, or of double thickness as shown at 8 in Fig. 5, in which latter case the flanges forming the bead are extended to the bottom of the groove, while in the former case the; bead flanges are de- The sides of the groove are flected inward to prevent a cutting of the fabric.

The jointfor the ends of the strip out of which the hoop is formed", is made by inserting sections of wire 4 in the hollows of the beads, and then clamping the beads around the wires whereby a secure joint is obtained, as shown in Figs. 5 "and 7. The

clamping action of the beads on the wires is preferably supplemented by'usin'g straight sections of spring wire, which must ncccs-- saril'y be flexed to the curve of the beads,

and 'theelastic tendency of the wires to straighten vserves to increase the binding action of the joint. The bottom of the groove is referably filled with some suitable resilient rictional material 5 as of rubber or leather, for the purposes hereinafter n mentioned.

- In the 'IIlO'difiGd' form of hoop shown in Fig. 6, the Web 3 is sharp ed to form the resuflicient energy in the spring ofthe ring to of the screw is preferably provided with the bcyon cessed channel 6 in the bottom of the groove, in which channel the resilient frictional material 5 is embedded; and the shoulders 7 formed by the sides of the channel,- serve to prevent the material from being displaced therefrom. In Fig. 7, a similar form' of 1100 is shown with the web 3 made of dou le thickness in a manner similar to the web shown in Fig. 5.

The clam ing ring 8 is preferably made of round resi ient wire and is divided or open on one side, and the free ends are referably bent to form the round eyes 9. he ring is preferably made so that the free ends will normally overlap each other, as shown by full lines in Fig. 2, to form a circle somewhat less than that ofthe bottom of the groovein the hoop, so that when the ring is opened or expanded as shown by broken lines in the same figure, to pass over the beaded' edges of the hoop, and then contracts in the groove of the hoop, there will yet remain compress the fabric 10 with some degree of firmness against the resilient frictional -ma-' terial in the bottom of the groove, as shown. in Figs. 4 and 6, but at the same time permits the fabric to be drawn one way or another to be pro erly adjusted and stretched on the hoop. n this relation of the arts,- the ring and the hoop are preferab y so shaped that there will be no clamping of the fabric between the ring and the sides of the groove in thehoo M Theclamping fever ispreferably formed U-shaped with the side plates or arms 11 joined at one end by the yoke 12, in which yoke is provided the adjusting screw 13. The lever is hinged by its arms to one end of the ring, preferably by means of the pivot 14passed throu h the eyes of thering, and the inner end 0 the screw is adapted, by a proper adjustment of the screw, to engage the farther side of the eye on the other end of the ring, which eye acts as a cam to draw and clamp the ends of the ring toward each other, as shown in Fig- 2. The outer end knurled spherical head 15, by means of which the screw is readily adjusted by the thumb and finger. It is evident that by shapin the cam so that the screw will pass a dead center, as shown in Fig. 3, the ring can be locked in its clamped position and will not be loosened by the ordinary use of the frame. p

T he arts are so proportioned and arranged that a ter the ring has been laced in position around the hoop and tiie intervening fabric 10, as shownin Figs. 4 and 6, a further contraction of the ring by the closing ofthe lever, serves to clamp the fabric between the ring and the hoop along two zones of contact against. the opposite walls ofthe groove, whichpositive clamping action is permitted by a compression ofthe resilient frictional material in the bottom of the groove, as shown, and the wedging of the round-wire groove. V

It will be understood that the use of the resilient frictional material in the bottom of the groove is not essential to the other features of the invention and that the same can be dispensed with when the thicker fabrics ring between the converging sides of the dent that very fine and delicate fabrics can be held in the frame with sufiicient firmness by adjusting the rin to com ress the fabric against the resilient frictiona material withoutmuch, if any, clamping of the fabric between the. ring and the sides of the hoop groove. And finally, it will be understood that the use of sheet metal for the hoop is not essential to the other features of the invention, although such material is preferred for conveniently shaping the beads and the web portions thereof. l

What I claim as my invention, and .desire to secure by Letters Patent, is

1.
